[0002] After the traditional pouring of structural columns on each floor, rotten edges and roots may occur. This is mainly due to loose joints of the formwork, loose grouting at the joints, loose connection between the bottom edge of the formwork and the pedestal, and loss of grout on the concrete surface during vibration. When the leakage is small, "burrs" appear at the corners, and severe leakage causes honeycomb surface. In addition, the arrangement of attached vibrators too densely, too low, and too close to the joints is also a cause of rotten edges and roots. Repairing again wastes manpower, material and financial resources. In addition, cracking of the internal cracks under the column is inevitable, and cracking will occur again after repair.
